| Apr 12, 2021 at 21:10 | comment | added | Dima Pasechnik | I tried reading Serre's 13.2, but I am stuck in his construction of an involution $\sigma:=\phi v^{-1}$ at about one page from the start. I don't understand why $\phi$ and $v$ commute, as claimed there (I think in general they won't). | |
